◆ getGenerator()

virtual const Matrix<double>& bpp::SubstitutionModel::getGenerator ( ) const
pure virtualinherited
Returns
The normalized Markov generator matrix, i.e. all normalized rates of changes from state i to state j. The generator is normalized so that (i) $ \forall i; \sum_j Q_{i,j} = 0 $, meaning that $ $ \forall i; Q_{i,i} = -\sum_{j \neq i}Q_{i,j}$, and (ii) $ \sum_i Q_{i,i} \times \pi_i = -1$. This means that, under normalization, the mean rate of replacement at equilibrium is 1 and that time $t$ are measured in units of expected number of changes per site. Additionnaly, the rate_ attibute provides the possibility to increase or decrease this mean rate.

Parameters
ithe index of the state in the model.
stateAn observed state in the sequence/site.
Returns
1 or 0 depending if the two states are compatible.
Exceptions
IndexOutOfBoundsExceptionif array position is out of range.
